Yet most people in Northern Ireland still seem to want to remain part of the United Kingdom. A BBC poll earlier this year suggested that just 17% of people in Northern Ireland want to leave the United Kingdom.
Dry ice is made from carbon dioxide gas. The carbon dioxide gas is pressurized and cooled to form liquid CO 2.The liquid carbon dioxide is injected into either a block press or pelletizer. These dry ice production machines have chambers in which, once released to atmospheric pressure, the liquid carbon dioxide converts to dry ice snow and carbon dioxide gas.he carbon dioxide gas is pressurized and cooled to form liquid CO 2.

Living organisms are composed primarily of carbon, oxygen, and hydrogen. Other elements in living matter include calcium, nitrogen, phosphorus, potassium, and trace amounts of other elements. Water is made up of hydrogen and oxygen. The oceans also contain salt, made up of sodium and chlorine. The atmosphere is mostly made up of the element nitrogen, existing in diatomic form (N2). It also includes oxygen, carbon (in carbon dioxide) and a small amount of other elements.
